Social media tools developer Yammer now integrates with Seesmic Desktop 2, a free desktop client that enables users to view multiple content streams from an array of social networking sites such as Facebook, Twitter, and LinkedIn.

"If you're a Yammer user, you know how powerful an internal collaboration tool can be for the productivity of a team. Now, that productivity you've come to love on Yammer.com is seamlessly tied into your social media dashboard on Seesmic," said Seesmic on its company blog. "With an internal network like Yammer alongside external networks like Twitter, Facebook, and anything else you can imagine, you'll be amazed by how slick the integration really is. With one click, information that was once external now becomes an actionable piece of data within your internal network."

Through the integration, which currently is in public beta, Yammer users now can access their Yammer feed -- including their company feed, replies, direct messages, sent messages, liked items, bookmarked items, and RSS feeds -- from the Seesmic desktop application via a mobile device, a desktop computer, or the Web. In addition, users can search their Yammer network with any keyword or phrase, and may post new messages to Yammer, including support for attaching files, the company said in a blog post.

"We've heard from users that a lot of them want a desktop client that can run Yammer and Twitter and things like that in multiple columns or one client," David Sacks, CEO of Yammer, told InformationWeek. "We didn't want to build that ourselves because feeds between services isn't what we do. Seesmic was interested in doing this. Seesmic's been very forward-looking. They're ahead of the curve in terms of aggregating feeds from other players."

Yammer users also can reply to, bookmark, and like any messages in a feed, view other users' profiles, and follow them from each individual's profile page, as well as update their Yammer profiles directly from Seesmic Desktop 2.

"Using Seesmic's ability to cross-post to several networks, you can now post Yams (when appropriate) to external networks," Yammer said. "We truly hope that you will enjoy this integration, and that it will bring you additional efficiency that you have come to expect from both companies' products."

The plug-in is listed in the Seesmic marketplace.

When it debuted in September 2010, Seesmic Desktop 2, which is written in Microsoft Silverlight, supported more than 40 customizable plug-ins for content streams ranging from social media heavyweights such as Facebook and Twitter, to Salesforce Chatter and eBay. The SAP company also spurred its growth through the 2008 acquisition of Twhirl, a desktop Twitter client, and its January 2010 purchase of Ping.fm, a service that allows users to publish content to over 50 social networks with a single click.

For its part, Yammer, which first opened its doors in 2008, is now used at 90,000 companies and organizations, including more than 80% of the Fortune 500, according to the company.
